Abstract
An electroluminescent device improved in brightness is disclosed. The electroluminescent device comprising sequentially stacked layers having an optically transparent material on at least the viewing side of the structure comprises a luminescent layer based on a Group II-III-VI compound host material with an element acting as a luminescent center added therein, wherein a Group II element having an ion radius differing from that of the Group II element constituting the compound host material is further added in the luminescent layer.
